Answer
The relative risk is (7/(7+124))/(1/(1+78)) which is equal to 4.22. This means someone who is exposed is 4.22 times as likely to develop the disease as someone who is not exposed.

I guess I'll get this started again:
What are the reasons for investigating an outbreak?

Try again!
Answer here if you're stuck
to figure out if a common infectious agent/organism cause this outbreak, to prevent additional cases from the same source, to tell how to prevent this problem in the future

Okay (I cheated and read your answer), that makes sense. I guess I'll ask now (although I technically didn't answer correctly). :)

Answer
pathogen → reservoir (can be nonhuman or human) → portal of exit → mode of transmission (indirect or direct) → portal of entry → susceptible host (always human)
